This invention relates tonew vand useful improvements in power mechanism and has for its primary object to provide such a device that embodies certain novel and peculiar features in the details of construction as well as the relative disposition of parts hereinafter' more clearly set forth,

illustrated in the drawing,l and set forth inthe appended claims. Y y

A further object of the invention is to provide a mechanismr for operatingvvery heavy machinery at `a uniform low rate of speed with the least expenditure of power in operating the invention andalso to provide a device in which tliegseveral elements are compactly arranged and assembled.

Other objects and advantages will become apparent as the nature of the invention Y.

is better understood, the same comprising` the novel form, combination and arrangement of part-s hereinafter more fully de-' scribed, shown in the accompanying draw# ing and claimed. f

In the accompanying drawings wherein like numerals indicate like parts throughout: l

Figure l is a side elevation of a power transmitting mechanism constructed in accordance with the present invention,

Now having lparticular reference to the drawing, myV novel mechanism constitutes the provision of a suitable supporting frame' 5 journaled throughbearings upon the upper ends of which is a power take-olf shaft G.

Keyed to this shaft within said frame 15 is y a power wheel 7 consisting of a pair vrof. spaced rims 8-8 interconnected vat .their centers by a hub'9. The linner faces of ythese f rims are 'formed with'rails 10'-10 as more clearly indicated inFig. 2.`

Mounted within the wheel V for operating the same is a power device consisting'of an electric motor 1l mounted upon 'av suitable.

framerlQ that is arranged between the rims A. 84-.8 ofthe wheel as also'clearly'indicated in shaft within the motor Vare equipped lwith,

Fig. 2. The opposite ends of theV armatured bearing gears 13--13 of predetermined size,

said bearing gears vbeing* in mesh withf smaller bearing gearsv 14-'14 aty the front and rear thereof and opposite sidesy of the Y motor, said last-mentioned gears `14C-.414 l being respectively in mesh with still further gears 15-15 upon the opposite ends ofl axles Fig. 2 is a detailed verticalsection thereof..v

V162-16 .journaled transversely across ythe vopposite ends of the frame 12 and upon with a suitable source of electric energy y and when the circuit to the motor is completed,` the wheels 17 will be caused to rotate in the same direction obviously rotating the wheel around said powery device which rotation of the wheel will be imparted`to the shaft from which the power may be taken in a desirable manner. y It will be seen that I have'provided a highly novel, simple and efficient form of power transmitting mechanism that is well adapted for all of the purposes heretofore designated. Even though I have herein shown and described the invention as consisting of certain detailed structural elements, lit is nevertheless to be understood vthat some changes may be made therein Having thus describedimy invention, what IY claim as new anddesire tosecure by Letters Patent is:

`1. In a power transmitting mechanism ofA the character described, a supporting frame,

va shaft mounted for rotation'upon the frame,

a pair of rims, a hub keyed to the shaftand l torwhich said pair of rims are connected, said rims being in spaced relation to each other, rails provided on'tlie inner faces of the rims, ,a power embodying means for said rim, ksaid means yconsisting of an electrical motor, aframe forsupporting said'electric motor, traction` wheels at opposite sides of the inotorrframe at the frontand rear ends thereof in tractional driving relation withy f the rails, and driving connections between the traction wheels and the electric motor'.
